To all `whom z't may Concern Be it known that I, FRANK A. ALLINGER, a citizen of the United States residing at Los An eles, in the county of laos Angeles. State ox California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

This invention relates to a hydrocarbon burner and particularly pertains to a burner especially adapted for use on locomotives.

It is the object of this invention to provide a burner Which will thoroughly atomize and mix the constituents of the hydrocarbon fuel so that it will be burned uniformly and complete combustion effected so that no smoke or deprsits of solid mattei' will result.

A further obiect is to provide a burner so constructed and arranged that steam will be thoroughly mixed with the liquid fuel within the burner before it leaves the burner tip and in which the mixed steam and oil will be caused to have a whirling movement within the burner, whereby thorough mixing of the fuel and the steam will be effected.

Another object is to provide means ,for ejecting the atomized mixture from the burner whereby it will be spread and evenly discharged into the furnace.

It is also an object to provide means in the burner for preventing such oil as may not be atomized therein from flushin out at the burner nozzle when the locomotive is quickly stopped.

A further object is to provide a hydrocarbon burner for locomotives consisting of few parts which may be readily taken apart and reassembled and which canbe readily cleaned when occasion requires, but which is not liable to become clogged o r obstructed.

A further object is to provide means for maintaining the floor of the mixing chamber of the burner in a heated condition, whereby the heavier constituents of the oil in passing thereover will be heated and rendered more fluid so as to facilitate its mixing with the previously volatilized fuel and steam and thoroughly commingling therewith at the discharge nozzle of the burner.

The invention is illustrated in the accompanying drawings, in which:

Figure 1 is a View of the burner in side elevation partly in vertical section. Fig. 2 is a horizontal section and lan view on the line 2-2 of Fig. 1. Fig. 3 1s a rear end view with parts broken away. Fig. 4 is a detail cross section on the line 4 4 of Fig. 2 as seen in the direction indicated by .the ar rows. Fig. 5 is a front view looking into the burner nozzle with parts broken away. Fig. 6 is a diagram in plan illustrating the application of the invention.

More specifically, 10 indicates the main body portion of the burner which is formed of cast metal in one piece and is substantially rectangular in outline. This body member lO-is formed with a longitudinally extending cylindrical chamber 11 which opens at the rear end of the body member 10 and is adapted to receive an oil feed pipe 12; the inner end of the chamber 11 opening to an enlarged mixing chamber 13, the `bottom 14' of which chamber 13 is slightly dished and is provided with transverse rifties 15.

The bcttom wall or fioor 1l of the chamber 13 terminates short of the outer end'o'f the body member 10 in a downwardly extending vertical wall 16; transverse ribs 17 being formed at the end of the bottom wall 14 and spaced apart at their inner ends to yform a restricted passage 18 therebetween.

The topl wall of the chamber 13 is inclined downwardly at a point above the outer end of the bottom wall 1l and has a vertical portion 19 spaced forward ofthe vertical wall 16 on a plane above the upper edge of the latter which connects with a horizontal wall extending outwardly to the end of the body -member 10 on a planeA approximately that of the outer portion of the bottom wall 14.

Formed on the underside of the body member 10 and extending beneath the bottom wall 14 is a chamber 2O which is extended upward on opposite sides of the cylindrical walls of the chamber 11; the chamber 20 being closed on its underside by means of a base plate 2l secured to the body member 10 by means of stud bolts 22.

The base plate 21 conforms in outline to the body member 10 `and is extended beyond the forward edge of the latter to form a distributing plate; the outer portion of the plate 21 projecting beyond the vertical wall 16 coiperating with the top and side walls of the outer portion of the chamber 13 to form the burner nozzle.

Formed in 4the wall 16 and leading from the chamber 2O is a series of small apertures 23 which are inclined downwardly from the chamber 20 toward the upper face of thc late 21 so as to direct steam from the chamer 20 against the plate 21 and thereby cause it to spread laterally at the point of dischargeifrom the burner nozzle. Steam is admitted to the chamber 20 through a pipe 24 connecting with a suitable source of steam ber 11 through the bore 26 it will be caused to have a whirlin movement so as to advance the oil disc arged from the pipe 12 with awhirling motion on a spiral path of travel-throughout the length of the charnber 11. j r

The operation `of the invention is as follows: Oil is delivered to the chambers 11 and 13 through the pipe 12 and Steam is delivered to the chambers 11 and 20 through the pipes 24 and 27. The steam entering thc chamber 11 eccentrically adjacent thepoint where the oil is delivered to the latter acts to break up the oil and advance it in a whirling spiral path through the chamber 11 from whence the commingled oil and steam are dis charged into the chamber 13 where the steam and atomized oil are expanded, then deflected downwardly by the inclined portion of the top wall of the chamber 13 'against the vertical wall 19 and downwardly, thence outwardly through the nozzle opening of the burner. The heavier particles of oil not readily commingled with the steam in the .chamber 11 are advanced onto the floor 14 of the chamber 13 where they are subjected to the action of heat and thus rendered more I fluid soV as to be carried forward with the steam and atomized particles of oil and discharged from theburner. The riilies 15 and the ribs 17 serve to prevent too free ilow'of the heavier oils across the fleor 14. The bottom or floor 14 and the walls of the chamber 11 are heated by the action of the steam in the chamber 20, which steam is discharged from the chamber 20 through the inclined apertures 23 and directed through the discharge end of the burner nozzle together with the atomized fuel and vapors discharged from the chamber 13; the steam jets discharged from the apertures 23 serving to evenly spread and diffuse the atomized and partially vaporized fuel in such manner that complete combustion is effected, thereby obviating smoke and deposits of solid matter.

What I claim is:

1. A hydrocarbon burner, comprising \a body member formed with an expansion and larged intermediate mixing chamber connecting with the discharge end of the burner, means for vdelivering oil to the outer end of thecylindrical chamber, means for delivering steam to the cylindrical chamber eccentrically thereto and to' the direction of iow of oil in the chamber at a point in front of the point of deliveryof, the oil to the chamber, -Whereby the oil and steam will be advanced. spirally through the cylindrical chamber, into the mixing chamber and thence discharged from the burner, and means for mixing a second volume of steam with the mixture formed in the burner at the discharge nozzle thereof.

1 3.A A hydrocarbon burner, comprising a body `member having a steam chamber on the underside thereof terminating in an apertured wall adjacent the discharge end of the burner and havinga cylindrical chamber and an expansion chamber connecting therewith arranged above the steam chamber with the expansion chamber opening at the discharge end of the burner beyond the apertured end Wall of the steam chamber, means for delivering oil to the cylindrical chamber, andmeans for delivering steam to the cylindrical chamber eccentrically thereto.

4. A hydrocarbon burner, comprising a. body member having a steam chamber o the underside thereof terminating in an apertured wall adjacent the discharge end of the burner and having a cylindrical chamber and an expansion chamber connecting therewith arranged above the steam chamber with the expanslon chamber opening at the dis- Y charge end of the burner beyond the apertured end wall of the Ysteam chamber, means
